Maybe you should use ComboBox (or other control) to let a user select approciated picture format himself?

... Then enlarge your buffer, for example, from 1024 to 10240 and repeat testings. One for the 1024 buffer and another for the 10240 buffer. Vladimir Grigoriev

... know can you use ERROR object with WIN API FILECOPY() function? The Clipper function __FILECOPY() builds ERROR object inside itself. Vladimir Grigoriev

I don't remember exactly but COPY FILE (or strictly speaking the corresponding function from EXTEND.LIB) uses a small buffer. By using fread() and fwrite() you can define a buffer as large as the maximum Clipper virtual segment size i.e. 0FFECh.

Thanks, but I stopped at Used.
If a object is declared but not used yet (i.e. seek() method was not executed) oFileSeek:used == .F.
If at least one seek() was executed (not important if it found a file or did not) oFileSeek:used == .T.

And you consider that TYPE( "ABS()" ) and ? TYPE( "ABS() + UNDEFINED()" ) both return "UE" is correct?

Vladimir Grigoriev

... FUNCTION DEFINED() RETURN ( NIL ) UI UI UE UE U U UE The last result "UE" destroys all concept to use TYPE( cExp ). Vladimir Grigoriev

Hi
How to determine in Clipper program that a specified by a user function (for example through GET command) exists?
I.e. a user inputs a macro expression containing function name &SomeUDF and there is a need to determine does exist a function with name SomeUDF() or does not.

I don't like lCompleted and lFinished on the same reason as lDone.
Also I think over lNew and something similar...
Vladimir Grigoriev

Thanks Enrico.
lExecuted is more suitable.
I wil wait a little. Maybe another suggestions will be.

... say with the instant variable that no any search method was executed. That I only defined an object but did not yet do any real seaching. Vladimir Grigoriev

Here is URL for downloading the (very simple) example.

... in this case at least one searching is done So how to name a logical variable which will say if at least one searching is done or not? Vladimir Grigoriev
